Bede is unable to reply until next week, so I'll send a reply on his behalf.
Both 4.2 and 4.3 were tried, with the observation that in 4.3 much less of
the colourmap is used. However, the our apps were still running out of
space with 4.3.
Do you know what the config option is for disabling the Render extension at
runtime in 4.3? I can't find it described in the XF86Config man page.

Which version of XFree86 are you using ?
In 4.2 the RENDER extension uses most of the colours in 8bit mode;
you can disable it at compile time.
I think I've seen a config option which disables the Render extension
at run time in 4.3, but now the extension isn't quite as greedy, so there
is less need for it.
